An alkyl halide (R X) reacts with Na to form 4, 5-diethyloctane. Compound R X is
CH3(CH2)3Br
CH3(CH2)2CH(Br)CH2CH3
CH3(CH2)3CH(Br)CH3
CH3(CH2)5Br
B.
CH3(CH2)2CH(Br)CH2CH3
Since, the alkyl halide RX gives 4, 5-diethyloctane, when reacts with Na, it must be CH3(CH2)2CH(Br)CH2CH3. The reaction is known as Wurtz reaction and is written as-
